Custom webpack config - DefinePlugin throws error "Cannot read properties of undefined (reading 'get' )

[roldengarm]

I'm trying to add a custom plugin to set some custom variables. In webpack.extend.js I've added:

const webpackConfig = {
  plugins: [new webpack.DefinePlugin({
    'VARIABLE': '"VALUE"'
  })]
}

However, getting an error at DefinePlugin.js: 292

compilation.valueCacheVersions.get(VALUE_DEP_MAIN)
"TypeError: cannot read properties of undefined (reading 'get')"

I appreciate you're busy, hopefully you can shed a light on this, thank you.

Usually with DefinePlugin, you should do JSON.stringify, i.e.:

const webpackConfig = {
  plugins: [new webpack.DefinePlugin({
    'VARIABLE': JSON.stringify('VALUE')
  })]
}
